Enesim is said to be similar to the Fog Framework and started out as a research project to optimize the Enlightenment Foundation Libraries, but then ended up becoming a project in its own right. The Enesim graphics framework supports vector and raster-based graphics, is considered highly-extensible, supports OpenCL and OpenGL renderers along with a software-based fall-back, and multi-threading support. The SVG renderer for Enesim is also said to be significantly faster than other common SVG libraries.
Also being worked on in conjunction with the core Enesim library are several other components: Eon (an Enesim-based tool-kit), Ender (an object-oriented description system), Emage (a sync/a-sync image loading system), Etex (the text renderer), Escen (an animation system), and Egueb (providing the DOM, SVG, and CSS parser/renderer).
Those wishing to learn more about the Enesim graphics framework can find it on Google code. The getting started page offers a more extensive overview of the LGPL-licensed project.
